Professor Thomas Lumley

Chair in Biostatistics

In: Statistics » Faculty of Science

Biography

I attended Monash University (B.Sc.(Hons) in Pure Mathematics), the University of Oxford (M.Sc. in Applied Statistics) and the University of Washington, Seattle (PhD in Biostatistics). I spent twelve years on the faculty of the Department of Biostatistics at the University of Washington, and then moved to Auckland in 2010. I am still an Affiliate Professor at the University of Washington.

Research | Current

My research interests include

Semiparametric models
Survey sampling
Statistical computing
Foundations of statistics
and whatever methodological problems his medical collaborators come up with -- currently, multiple imputation on big datasets

Resources

The survey package for R is a fairly comprehensive system for analysis of data from complex probability samples.
I have written a book on survey analysis, published by Wiley.

Potential student projects

Likelihood of the empirical distribution function as an approach to Bayesian analysis of survey data.
Mixed models under complex sampling -- and maybe network models, too
Survey software: design and implementation of various things for the survey package in R or for database backends. Graphics, probability distributions, regression models, multivariate methods...
Software for teaching:design and implementation of interface to R for teaching introductory biostatistics
How many categories? Data on, say, hospital visits, can be categorized coarsely (eg lung problem) or much more finely (eg infection by pencillin-resistant Strep. pneumoniae). When the categories are too fine the sample size in each one is too small to see patterns; when they are too coarse, the patterns are masked by events that don't really belong. The idea is to build a tree structure that uses all levels of categorization simultaneously in a Bayesian model.
